Key words: reef, famennian stage, fractured carbonates, upper Devonian.
Oil reserves of Volga-Ural oil province are sufficiently depleted at present time. Particularly, degree of initial oil reserves depletion of Samaraneftegaz JSC now exceeds 70%. In such conditions the process of Company resource base  replenishment becomes very important. This process can be conducted as by purchasing of new license areas, so as by the search of so-called “missed”  reservoirs and additional exploration program on developed fields. This article  describes the discovery of oil-bearing reservoirs in carbonate reefs of Famennian  stage on the territory of Samara region and also the prospective of analogous  reservoirs discovery in the region. Additionally the main principles of search program are described and the main results of search for the oil fields of  Samaraneftegaz JSC in the 1-st quarter of 2013 are provided.
